Solution

1. Preparation

Gather tools and materials: rags, a flashlight, UV leak detection dye, and UV light.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Inspect Engine Bay

Open the hood and visually inspect the engine components.
Use the flashlight to look for any pooled oil or residue around the oil filter, oil pan, and valve cover.
Clean any visible oil spots to better identify new leaks.

3. Check Oil Level

If equipped, remove the dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the oil level.
If low, add the appropriate oil type according to Tesla specifications.

4. Use UV Dye

If leaks are suspected, add UV leak detection dye to the oil.
Allow the vehicle to run for a short period to circulate the dye.
Use a UV light to check for glowing spots in the engine bay and undercarriage.

5. Repair Leaks

Depending on the source of the leak, replace gaskets, seals, or the oil filter as necessary.
Ensure all bolts are tightened to manufacturer specifications.
